Question

Micturition is carried out by a reflex.

• A. True
• B. False

Answer 1

The correct option is A True

In vertebrates, most sensory neurons do not pass directly into the brain, but synapse in the spinal cord. This allows for faster reflex actions to occur by activating spinal motor neurons without the delay of routing signals through the brain.

The micturition reflex is ultimately generated from the level of the spinal cord after it receives reflexes from the pontine region in the brain. Once the bladder and the urethra receive the signals to empty the bladder, the two sphincters (external and internal) relax and the detrusor muscle causes the contractions of the bladder.

So, the correct option is 'True'.
